Chapter 12: Q 80. (page 1184)

In the following exercises, determine if the sequence is arithmetic and if so, indicate the common difference.
$11, 5, - 1, - 7 - 13, - 19, \dots$

Short Answer

Expert verified

The value of dis -6.

Step by step solution

Step 1. Given Information.

Consider the given information.

$11, 5, - 1, - 7 - 13, - 19, \dots$

Step 2. Find the consecutive difference of the sequence.

Find the difference between the consecutive terms.

$\begin{array}{rcl} 5 - 11 & = & - 6 \\ - 1 - 5 & = & - 6 \\ - 7 - (- 1) & = & - 6 \\ - 13 - (- 7) & = & - 6 \\ - 19 - (- 13) & = & - 6 \end{array}$

Since the common difference is the same.
The value of the common difference is $d = - 6$ .

Step 3. Conclusion.

The sequence is an arithmetic sequence and the common difference is d=-6.
